Commercial General Liability (CGL) insurance is a type of business insurance policy designed to protect companies from financial losses arising from third-party claims related to bodily injury, property damage, personal injury (such as libel or slander), and advertising injury (such as copyright infringement or false advertising). It is the standard liability policy for most businesses, covering incidents that occur on or off premises during business operations.
The origins of CGL insurance trace back to the early 20th century, evolving from basic liability coverage as businesses recognized the need for protection against lawsuits. In the United States, liability insurance gained prominence in the 1880s in response to increasing lawsuits related to industrial accidents and property damage.
Historical CGL policies have been crucial in covering long-tail claims, such as environmental cleanup, often leveraging older "occurrence-based" forms that trigger coverage based on when the incident occurred, not when the claim is filed. Over time, exclusions for intentional acts and professional errors were added, shaping modern policies amid rising litigation and social inflation.
Coverage of Commercial General Liability Insurance
CGL policies typically provide coverage on an occurrence basis, meaning claims are covered if the incident happens during the policy period, even if reported later. Key coverage areas include:
Coverage Type | Description |
Bodily Injury | Medical expenses, lost wages, and legal fees for injuries to third parties caused by business operations, products, or premises. |
Property Damage | Costs to repair or replace third-party property damaged due to business activities. |
Personal and Advertising Injury | Claims for non-physical harm, such as defamation, invasion of privacy, or misleading advertising. |
Legal Defense | Attorney fees, court costs, and settlements (up to policy limits) for covered claims. |
Coverage limits are often set at $1 million per occurrence and $2 million aggregate, but can be customized.
Common CGL claims illustrate the policy's practical applications:
Slip-and-Fall Accidents: A customer slips on a wet floor in a retail store, suffering injuries; CGL covers medical bills and legal fees.
Property Damage: A contractor accidentally damages a client's equipment during work; the policy pays for repairs.
Product Liability: A defective product causes harm to a user post-sale; coverage includes settlements and defense.
Defamation or Slander: A business is sued for false statements in advertising; CGL handles personal injury claims.
Customer Injuries: Non-employee accidents on premises, like a trip over merchandise, leading to bodily injury payouts.
Burglary/Theft-Related Claims: While not direct coverage, related third-party liabilities (e.g., if theft leads to customer data breach) may trigger add-ons.
Storm Damage or Auto Accidents: Often tied to premises liability or operations, with CGL covering third-party aspects.
These examples highlight why CGL is vital, with burglary/theft accounting for 54% of business claims overall.
Benefits of Commercial General Liability Insurance
CGL insurance offers several key advantages for businesses:
Financial Protection: Shields against costly lawsuits, which can exceed $100,000 on average for bodily injury claims.
Legal Support: Pays for defense costs, even if the claim is unfounded, reducing out-of-pocket expenses.
Reputation Management: Helps maintain business continuity by covering settlements that prevent reputational damage.
Contractual Compliance: Often required by clients, landlords, or contracts to mitigate risks.
Peace of Mind: Covers unexpected third-party incidents, allowing focus on core operations.
Add-ons and Exclusions
CGL policies include standard exclusions to limit insurer risk, but add-ons (endorsements) can expand coverage.
Common exclusions prevent coverage for foreseeable or non-business risks:
Exclusion Type | Description |
Intentional Acts | Injuries or damages expected or intended by the insured (e.g., assault). |
Professional Services | Errors in advice or services (covered by errors & omissions insurance). |
Contractual Liability | Assumed liabilities beyond standard business operations. |
Product Recalls | Costs to recall defective products. |
Pollution | Environmental damage from pollutants (unless added). |
Employment Practices | Employee-related claims like discrimination (covered by EPLI). |
Optional endorsements to broaden protection:
Add-on | Description |
Cyber Liability | Coverage for data breaches or digital injuries. |
Umbrella/Excess Liability | Extends limits beyond standard policy (e.g., +$1M). |
Hired/Non-Owned Auto | Liability for vehicles not owned by the business. |
Products-Completed Operations | Enhanced coverage for post-sale product issues. |
CGL Insurance Cost
The average annual premium for CGL insurance is approximately $500–$2,000 for small businesses, with monthly costs ranging from $40 to $100. Costs vary widely based on business specifics, with larger firms or high-risk industries paying $1,000–$5,000 or more annually.
Premiums are influenced by multiple factors (detailed below). In 2025, the global liability insurance market is valued at approximately $290.5 billion, with projections for continued growth driven by increasing litigation and economic factors.
Premium Factors
Premiums for Commercial General Liability (CGL) insurance are determined by assessing the risk profile of a business, which influences the likelihood and potential cost of claims.
Insurers calculate premiums using a base rate multiplied by exposure units (e.g., revenue, payroll, or square footage) and adjust for specific risk factors. Below are the key factors impacting CGL premiums, along with their typical effects:
Factor | Description | Impact on Premium |
Business Type/Industry | The nature of the business determines risk level. High-risk industries (e.g., construction, manufacturing) face greater exposure to bodily injury or property damage claims compared to low-risk sectors (e.g., consulting, retail). | High-risk industries pay 2–3x more than low-risk ones. For example, construction firms may pay $2,000–$5,000 annually, while consultants pay $500–$1,000. |
Business Size/Revenue | Larger businesses with higher revenue or more employees have greater exposure to claims due to increased interactions with third parties. | Premiums scale with revenue; e.g., a business with $1M in revenue might pay ~$800–$1,200 annually, while $5M revenue could increase this to $2,000–$4,000. |
Location | Geographic areas with higher crime rates, litigation tendencies, or regulatory requirements (e.g., urban centers) increase risk. Regional regulations, like Hong Kong’s risk-based capital regime, also affect costs. | Urban/high-crime areas add 10–20% to premiums. For example, a Hong Kong business may pay 15% less than a similar U.S. urban business due to lower litigation. |
Claims History | A history of frequent or severe claims signals higher risk, leading insurers to increase rates. | Prior claims can raise premiums by 20–50%. A business with multiple claims may see rates double compared to a claim-free business. |
Coverage Limits/Deductibles | Higher coverage limits (e.g., $2M per occurrence vs. $1M) or lower deductibles increase premiums, as insurers bear more risk. | Doubling limits (e.g., $1M to $2M) may increase premiums by 30–50%; a $1,000 deductible can save 10–15% compared to no deductible. |
Years in Business | Newer businesses lack a proven risk profile, making them riskier to insure. | Startups or businesses under 3 years old may pay 15–25% more than established firms with similar profiles. |
Risk Management Practices | Businesses with safety programs, employee training, or risk mitigation measures (e.g., security systems) are seen as lower risk. | Implementing safety measures can reduce premiums by 5–15%. For example, a retailer with surveillance may save 10% vs. one without. |
Number of Employees | More employees increase the likelihood of workplace incidents or interactions leading to claims. | Businesses with 50+ employees may pay 20–30% more than those with 10 or fewer, proportional to payroll size. |
Property Size/Operations Scope | Larger premises or broader operations (e.g., multiple locations, international trade) increase exposure to third-party risks. | A business with 10,000 sq. ft. may pay 20% more than one with 2,000 sq. ft.; international operations add 10–20%. |
Calculation of CGL Premiums
CGL premiums are calculated using a combination of exposure units, base rates, and risk adjustment factors. The process is standardized but tailored to each business’s profile.
Determine Exposure Base: Insurers use a measurable unit to gauge risk exposure, such as annual revenue, payroll, or square footage. For example:
Revenue: Common for service-based businesses (e.g., consulting, retail).
Payroll: Used for labor-intensive industries (e.g., construction, manufacturing).
Square Footage: Applied for premises-based risks (e.g., restaurants, warehouses).
Apply Base Rate: Each industry has a base rate per unit of exposure (e.g., $X per $1,000 of revenue or payroll). Rates reflect the inherent risk of the industry. For example:
Construction: $5–$10 per $1,000 of revenue.
Retail: $1–$3 per $1,000 of revenue.
Adjust for Risk Factors: Insurers apply modifiers based on the factors above (e.g., location, claims history, coverage limits). These are expressed as multipliers (e.g., 1.2 for high-risk locations or 0.9 for strong safety programs).
Include Additional Coverages: Add-ons like cyber liability or umbrella coverage increase the premium based on their specific rates.
Apply Discounts or Surcharges: Discounts for bundling (e.g., with a Business Owner’s Policy) or surcharges for prior claims adjust the final premium.
